Apartment Building
There 3 floors of an apartment building with 12 residents. A storm comes that causes the ceiling of the top floor to leak. So the residents on the top floor go to the second floor to ask those residents for shelter, but they can only allow double their occupancy and the rest have to go back up to their floor. The water gets to the second floor and those residents go to the first floor to ask the same thing and they get the same reply (They can only take double their occupancy). The question is, how many residents were on each floor before the storm so that there are equal number of residents on each floor after the storm?
